Check out a bike coop if you have one near you. I think in CA they call them bike kitchens (?) They're usually staffed by super rad people who love bikes and also love showing you stuff. Ones near me run mechanics classes (basic/advanced), wheelbuilding classes, and women's only classes. Or find a bike nerd friend to teach you a few things?

When I worked as a mechanic, I had no problem demonstrating to someone how I do things, with explanations. Inevitably, my slowed pace was still way faster than they could comprehend. Also, fixing bikes is one of those things you need to get dirty and learn hands on. These were simple things- changing flats, using qr levers, installing/removing wheels.
